Ill-equipped compared to the Noldor and highly independent, the Silvan Elves suffered heavy losses in the Battle of Dagorlad. Oropher and Amdír, with half of his forces, were cut off from the main force and perished in the Dead Marshes.[1]

The word Amdir, without the long í, is recorded as a word for "Hope", or "looking up", in Sindarin.[3]
However, the name Amdír with a long i may rather possibly derive from a shortened form of Sindarin dîr (meaning an "adult male"), chiefly used as ending in proper names.[4]

The King of Lórien is called Malgalad in one text, detailing the fate of the Sindarin kings in the Battle of Dagorlad. Christopher Tolkien argues that, since they are contemporaries and both described as Kings that died in the Battle of Dagorlad, they are likely the same.[1] It is unclear however which form was abandoned. Malgalad likely means "Gold-shine", from malt, "gold (the metal)"[5] and galad, "light, radiance, glittering, reflection (from jewels, glass or polished metal, or water)"[6] or "Golden-tree", from the outdated spelling of galadh.[7]
